Images on a plurality of adjacent maps are accurately connected without performing positional displacement at their connecting boundaries, thereby obtaining a single seamless image. A plurality of corresponding points to be connected are specified on adjacent images. The amount of movement for each picture element on the image is calculated in order to make the specified corresponding points coincide. All of the picture elements in the image which are to coincide are moved according to the results of the calculations.
